Food safety knowledge among 7th-grade middle school students: A report of a Brazilian municipal school using workshop-based educational strategies.

Practical methodologies that include food safety and hygiene education in pedagogical activities are strategies to prevent foodborne diseases (FBDs). Thus, the aim of this study was to investigate the knowledge of 7th-grade middle school students regarding food microbiology and food safety, and to apply workshop-based educational strategies that focus on scientific literacy. The students (144) were initially evaluated using a Likert-scale questionnaire (pre-intervention, Q0) with ten objective questions on microbiology and food safety.

Microbiological Quality and Prevalence of β-Lactam Antibiotic Resistance Genes in Oysters ( Crassostrea rhizophorae ).

The microbiological quality of oysters reflects the microbiological quality of their habitats because they are filter feeders. The objective of this study was to assess the bacterial composition of the edible oyster Crassostrea rhizophorae in urban and preserved estuaries. Particularly, we assessed the presence of pathogenic bacteria, investigated antibiotic susceptibility in bacterial isolates, and quantified β-lactam antibiotic resistance genes (bla, bla, and bla) via quantitative PCR of oyster DNA.
